Why doesn't the golang server send a response?

There is a golang server:

package main

import (
  "fmt"
  "net/http"
)

var i = 0

func receiveSend(w http.ResponseWriter, r *http.Request) {
  if r.Method == "POST" {
    sendedData := r.FormValue("sendedData")
    fmt.Println("My request is: ", sendedData)
    fmt.Fprintln(w,"sd")
  }
}

func main() {

  http.HandleFunc("/", receiveSend)

  http.ListenAndServe(":8000", nil)
}

And the page:

<!DOCTYPE html>
<html>
<meta charset="utf-8">
<script src="https://code.jquery.com/jquery-3.2.1.min.js" integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4="  crossorigin="anonymous"></script>


<body>
    <button id="send">Send</button>
    <p class="results">Ждем ответа</p>
  </body>
  

<script>
  var data;
  $('#send').click(function() {
    $.ajax({
      url: "http://localhost:8000",
      method: "POST",
      data : { sendedData: 'Hello'},
            success : function(data) {
                $('.results').html(data);
            },
    });
  });
  
</script>
</html>

The request to the server leaves, the server receives and outputs data, but does not send anything in response. With what it can be connected and where to dig?

I think the problem is in CORS

func receiveSend(w http.ResponseWriter, r *http.Request) {
  w.Header().Set("Access-Control-Allow-Origin", "*")
